Of course, the toon can be eaten raw, but when you eat it, you should eat the young shoots that have just grown out. If they are too old, they may not be digested well in the body and cause indigestion.
Note that if you eat too much raw toon, it may have a certain toxic effect. Toon contains nitrates and nitrites, in the human body nitrites and hemoglobin ions redox reaction occurs, generating low-valent iron ions, loss of oxygen-carrying capacity, so too much consumption of toon may appear hypoxia, the body is not good.
